Gabe-
I'd launch at about 1500, and try short shifting to second as you roll into
the throttle.
Just resist the urge to punch it to the floor for the first 20-30 ft
as you apply the throttle.
I launch at 1500 and ease up on the brake pedal as I roll into the throttle
with my Automatic.......I've gotten a best 2.279 as a 60'
time..........NOT BAD for a 4x4!
I set my air pressure at 30-32 PSI depending on the track condition.
Going any lower risks spinning the tire on the rim of a radial tire,
slicks on the other hand are meant to be run at lower pressures.
